OUR NO-COMPROMISE APPROACH TO CREATING THE BEST CYCLING CLOTHING IN THE WORLD IS NOWHERE MORE EVIDENT THAN IN THE 2019 FREE AERO RACE 4 BIBSHORT. THIS IS A PRODUCT THAT’S UNDERGONE 12 YEARS OF DEVELOPMENT AND REFINEMENT, WITH LITERALLY MILLIONS OF KILOMETERS ON THE ROAD.

- Doppio V construction in front for increased support and comfort
- Flat-lock stitching
- Progetto X² Air Seamless seat pad
The Free Aero Race short is the all-around race short we supply to Team Sky, as well as all race teams we’ve sponsored since 2007. But that’s not enough of a reason for you to just go out and buy a pair. Since these guys ride over 30,000 kilometers per year, we consider them ideal testers and continuously solicit their feedback. The difference is that we actually listen to them. And the good thing for you is that the pros are looking for comfortable shorts too, so this short is made to be minimalist and fast, but without sacrificing all-day comfort.
FOR THIS YEAR WE’VE MADE SUBTLE BUT IMPORTANT REFINEMENTS. THE SEAT PAD HAS BEEN UPDATED WITH A SOFTER, STRETCHIER AND TOTALLY SEAMLESS TOP LAYER. THE LEG GRIPPER IS ALSO STRETCHIER AND GRIPS BETTER YET ALLOWS FOR A BETTER-QUALITY SUBLIMATION PRINT. THE BIB STRAPS ARE BOTH LIGHTER AND MORE COMFORTABLE WHILE GIVING BETTER SUPPORT. OUR WEAR TESTERS ARE SAYING THIS IS THE BEST FREE AERO RACE YET.

Muscle Support and Speed
In re-engineering the Free we took a look at blood flow, providing just the right muscle support without constricting. The revolutionary Giro Air leg band provides more stretch and distributes the compression over a larger area. The body of the short uses 30% Spandex for excellent return.
We also looked at aerodynamics, optimizing boundary-layer airflow with the Giro Air leg band and the dimples on the side fabric. The wind tunnel says it saves 10 watts at 50 km/h, but you’ll probably want to go even faster because your aero advantage will only increase.
Confort and Fit
The best race short must be supremely comfortable. The new fabrics are all softer than the outgoing fabrics, especially the new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach. And we’ve engineered a new Carré yoke that makes the straps lie perfectly flat.
But the most important part of comfort is fit. As one of our pro testers said, “These shorts fit perfectly. They don’t move around. Everything is just right.”
